  1. 1. Future climate suitability of shade trees in cocoa agroforestry systems in West Africa and shade tree diversity’s impact on farm microclimate : A Minor Field Study

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Jonna Halonen; [2023]
    Nyckelord :species distribution modeling; cocoa agroforestry; shade trees; West Africa; microclimate; distributionsmodell; kakaoskogslantbruk; skuggträd; Västafrika; mikroklimat;

    Sammanfattning : Shade trees’ implementation into cocoa agroforestry systems in tropical West Africa has proven to have a high potential in increasing farm resilience and mitigating climate change. However, no studies have yet examined the potential future climate suitability for shade trees in the region, which is important when deciding which shade trees to implement. LÄS MER

  3. 2. On the road to grid stability - Using batteries in heavy vehicles and charging infrastructure as frequency reserves

    Master-uppsats, Lunds universitet/Produktionsekonomi

    Författare :Matilda Kjellström; Caroline Wuttke; [2023]
    Nyckelord :Case Study; Electrification; Frequency regulation; Energy reserve; Battery; Heavy vehicles; Vehicle-to-grid; Technology and Engineering;

    Sammanfattning : Background: Climate change and increasing threats that come with it fosters a need for changing from fossil sources of energy to renewable ones. Sweden aims to have net zero greenhouse gas emissions by the year of 2045. One of the sectors that need to take part in this shift towards fossil free energy is the transport industry. LÄS MER

  4. 3. Streamlining the flow of material through buffer simulation and multi-objective optimization, with regards to sustainability : A case study at Volvo Construction Equipment

    Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Daniel Nord; Alex Wernholm; [2023]
    Nyckelord :Multi-Objective optimization; Buffer Allocation Problem; Simulation modeling; FACTS Analyzer; Buffer allocation; Optimization; Buffers; Lean; Manufacturing; Streamlining; Sustainability; Flow of material; Design of Experiments; Gemba walk; Data visualization;

    Sammanfattning : This thesis will provide knowledge on how to maintain a well developed flow of material while at the same time finding an optimal level of capacities for buffers. Simultaneously, aspects that allow for positive sustainability practices will be regarded.  Buffers have a considerable impact on the performance of a production system. LÄS MER

  5. 4. Design of a 13-Bit SAR ADC with kT/C noise cancellation technique

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Shashank Keerthy Kumar; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : One of the main limitations of a Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) is the large input capacitance needed to achieve the desired performance. This large input capacitance increases the total area of the ADC and it imposes the use of a powerful buffer to drive it. LÄS MER

  7. 5. Evaluation of antioxidant effect of an algae extract on skin: in vitro study

    Kandidat-uppsats, Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV)

    Författare :Oday Al Mustafa; [2023]
    Nyckelord :Algae extract; antioxidant; DPPH; microalgae; ROS; skin covered oxygen electrode; skin;

    Sammanfattning : Algae extracts are used as cosmetic products and used as additives in specific foods because of their antioxidant activity. Reactive oxygen species (ROS) such as hydrogen peroxide and superoxide radicals are toxic on the skin and can be scavenged by antioxidants, which are abundant in microalgae. LÄS MER
